     But it was surprising that the variation of ratio, |M -/M +| does not cause the visible change in shear capacity of restrained beams,that is,the shear strength depends on a/h 0 only but not M/Vh 0 . Besides,it is found also that the stress of stirrup placed in central section of the “shear span a ” is always bigger than the stress in both end parts.
     但也惊奇地发现,支座负弯矩与跨中正弯矩比值的变化并未引起约束梁抗剪能力的明显改变,即其抗剪承载力只取决于a/h0而非M/Vh0.此外,还发现剪跨a范围内箍筋的应力分布总是中部大,两端小。

     In this paper, some of the problems are studied, as listed below:(1) In the previous theories of restrained steel beams, because the stress distribution in the model changes abruptly when it yields, the behaviour of restrained beams is not continuous when it changes from elastic to plastic. In this paper, a continuous development model of stress and strain is presented, through which the above problem is solved.

Based on the shear tests of 18 concentrated loaded reinforced concrete restrained beams without web reinforcement, the general rule of the shear strength of such beams was investigated. It was found that the shear strength varies with shear span ratio and moment ratio, that is in the same span the moments occurred in opposite directions would influence the shear resistance of the beam. The formula for computing the shear strength of reinforced concrete restrained beams without web reinforcement...

As the shear strength formulae in current Code 《TJ10-74》are not safe enough to be used in calculating continuous beams, restrained beams, and beams and columns of frame structures, the authors carried out experimental research of shear strength in reinforced concrete members with an inflection point under concentrated load, analysed data of the 170 internal and external shear strength tests of these beams and members loaded in an anti-symmetrical way, and approached factors influencing the...

As the shear strength formulae in current Code 《TJ10-74》are not safe enough to be used in calculating continuous beams, restrained beams, and beams and columns of frame structures, the authors carried out experimental research of shear strength in reinforced concrete members with an inflection point under concentrated load, analysed data of the 170 internal and external shear strength tests of these beams and members loaded in an anti-symmetrical way, and approached factors influencing the shear strength of the members with an inflection point, and the causes of its strength reduction. Finally, two corresponding formulae are proposed which agreed well with the test results.

鉴于我国现行《钢筋混凝土结构设计规范》中抗剪强度公式用于计算连续梁、约束梁和框架结构的梁和柱等构件常偏于不安全问题,本文进行了集中荷载作用下具有反弯点的钢筋混凝土构件的抗剪强度的试验研究,综合分析了国内外连续梁、约束梁和反对称荷载作用下构件的抗剪强度共170个试验资料,探讨了受荷时具有反弯点的构件抗剪强度的影响因素及其降低原因,并提出了两个建议计算公式,与试验结果吻合较好。

In the underground engineerings and hydro-structures, a great deal of reinforced concrete members with lower reinforcement ratio and without web-reinforcement are adopted. These members generally bear uniform loading and there frequently exists restrained bending moment at the support. But, until now, the test studying the shear behaviors of the reinforced concrete beam without web- reinforcement under uniform loading is not enough.

In the underground engineerings and hydro-structures, a great deal of reinforced concrete members with lower reinforcement ratio and without web-reinforcement are adopted. These members generally bear uniform loading and there frequently exists restrained bending moment at the support. But, until now, the test studying the shear behaviors of the reinforced concrete beam without web- reinforcement under uniform loading is not enough. This paper introduces a test about shear behaviors of 6 simply supported beams and 12 restrained beams, and a idea of "Equivalent Simply Supported Beam", This paper also describes some laws about shear behaviors of the reinforced concete beams without web-reinforcement and advances a formula for estimating the shear strength, which may serve for design purpose.
